  • ABSTRACT Wireless Sensor Networks (WSNs) consist of smallsensing nodes with capabilities-computation andwireless communications. There are severalcharacteristics of wireless sensor nodes that limit theirfunctionality. Due to the use of batteries Wirelesssensors often have limited energy. The total networkcapacity is limited by the use of unsophisticated wirelesslinks that limit the range, reliability, and throughput ofcommunication between nodes . Providing access to thesystem by proper authentication makes the system moresecure.
  • INTRODUCTION Wireless Sensor Networks Energy Minimization Advantages Applications
  • Existing System Base station . Energy optimization is not achieved. More prone to attacks. Usage of same key. Data transmissions are not reliable.
  • Proposed System Uses Hierarchal clustering. Energy Minimization. Secure Routing. Makes use of efficient Key distribution techniques. Data Transmissions between privileged users. Cost can be decreased.
  • Cluster Based Hierarchal Network  Hierarchal Architecture  Levels in the design  Base Station  Cluster Head  Sensor Nodes  Need for Clustering
